Currently, including in China, the industrial high-speed development maintains sustained rapid and healthy growth. At the same time, there is a large number of major engineering projects that need to improve economic efficiency. At this point, technological transformation is needed, and the same goes for product production, which also requires technical support. Therefore, smart type pressure transmitters and precision instruments have a large market demand. According to predictions, the average annual growth rate of demand in the next five years can reach more than 15%. With the development of economic technology, market demand is increasing, and the future outlook is bright.
From the perspective of the structural composition of widely used smart pressure transducers on the market, they mainly include microprocessors, sensors, digital-to-analog converters, and memory devices. The sensor primarily detects the measured signal, and the materials designed for specific applications have certain differences. The microprocessor, as the core part of the entire device, mainly performs comprehensive analysis and calculations on the data collected by the device. It conducts unit conversion, fault diagnosis, range adjustment, function calculation, and other operations on the detected signals.
First, wide range and large turndown ratio. Among the comprehensive characteristics of the smart type pressure transmitter is the feature of a wide range and large turndown ratio. Compared to conventional analog transmitters, the most prominent advantage of the smart pressure transducer is that it can effectively reduce inventory levels. It can also perform free range adjustments as needed without replacing the meter, without worrying about exceeding the range limits.
Second, easy maintenance and management. The smart pressure transducer uses a handheld communicator and smart transmitter communication. It can choose to connect at the location of the transmitter's terminal block on-site and at the terminal, ensuring the safety of the instrument maintenance staff. It ensures that the control room can reasonably adjust the transmitter's range, making equipment maintenance and management convenient.
With high and low-pressure side conversion function. The sensor's high and low-pressure side conversion function is mainly achieved by adjusting the internal parameters using a handheld communicator. It effectively converts data between high and low-pressure sides. Even after reconfiguration post-conversion, the overall status remains normal, which also effectively saves manpower and resources.
Generally, smart pressure transducers connect to the process through small diameter pipelines, which are called pressure guide lines. In some applications, these pressure guide lines may become clogged by substances or freeze due to cold weather, causing blockages. These blockages could lead to difficulties in pressure signal transmission. When such blockages occur, the signal indicated by the transmitter would differ from the signal before the blockage, and it is necessary to ensure that the transmitter output has not changed along with the actual flow for the problem to be detected. If one or two pressure guide lines are blocked, the standard deviation of the specific flow will change significantly, and the smart pressure transducer can effectively detect this change. This detection allows timely control of the blocked pressure guide line positions, facilitating fault finding and preventing the issue from escalating.
In many chemical industries, refining furnaces are important equipment used for incinerating different chemical production waste gases. Because many BTU coexist, the flame stability is not very good, which is also a sign of refining furnace flameout. By using smart pressure transducers, the noise of the chamber control pressure can be measured to detect flame stability. The measurement accuracy is generally high, enabling the detection of abnormal signals in the refining furnace, which allows relevant staff to correct problems timely and avoid flameout.
